Silicone sponge profile

Item No. SSE-005

Our Silicone Sponge Profiles are high-performance extruded rubber seals, engineered for exceptional durability and versatility. Available in both closed-cell and open-cell structures, they are specifically designed to deliver superior cushioning, sealing, and insulation performance—even in extreme temperature environments ranging from -55℃ to 250℃. These profiles feature low compressive force and excellent resistance to UV radiation and ozone, with a wide range of shape options and self-adhesive backing available to meet diverse application needs.

Key Features & Core Benefits

Premium Material: Crafted from high-quality closed-cell silicone rubber with a smooth outer skin, ensuring consistent performance and long service life.


Superior Environmental Resistance: Boasts high resistance to water, dust (meeting IP65-IP66 standards), 

UV light, and oxidation, making it suitable for both indoor and outdoor applications.


Exceptional Compression Performance: Offers excellent memory and a low compression set, 

maintaining its shape and sealing efficiency even after repeated compression.


Flexible Customization: Available in a variety of colors (including white, red, and black), 

sizes, and can be customized into specialized profiles upon request to match your unique requirements.

Complete Pallet Preparation for rubber extrusions
Complete Pallet Preparation for rubber extrusions

Standardized Pallets: Goods are stacked on heat-treated (ISPM 15) or plastic pallets, optimized for forklift handling. Rigid Corner Protectors: High-impact cardboard corner guards are applied to the full height of the stack. This prevents the straps from cutting into the rubber and maintains the vertical integrity of the pallet.
